Here's what it could potentially refer to:
* Typo: It could be a typo for "coprology," the study of feces.
* Made-up word: Someone might have invented the term "copography" for a specific purpose, perhaps in a fictional context or a humorous situation.
* Misunderstanding: You might have misheard or misinterpreted a word that sounds similar to "copography."
If you can provide more context, I might be able to help you figure out what you're looking for.
